Flora of North America species comparison

few to many, erect or ascending, unbranched, sometimes with inconspicuous, short, leafy axillary shoots, hairs spreading to erect, long, soft to stiff, mixed with shorter stipitate-glandular ones.

several to many, erect or ascending, often grayish, unbranched or often branched distally, glabrate proximally or hairy, especially distally, rarely glabrous, hairs sparse, spreading to appressed, usually curly, ± short, soft, sometimes mixed with sparse, short stipitate-glandular ones.

green, sometimes purple-tinged, margins sometimes red-brown, linear or narrowly to broadly lanceolate to narrowly oblong, oblanceolate, or ovate, 1–8.5 cm, not fleshy, margins plane or wavy, involute or flat, (0–)3–5(–7)-lobed, apex acute to rounded or acuminate;

lobes ascending, linear to narrowly lanceolate, much narrower than mid blade, apex acute to rounded.

often grayish or purplish, linear to narrowly lanceolate or narrowly oblong, (1–)2.5–5(–6.7) cm, not fleshy, margins plane or wavy, involute, deeply (0–)3–5(–7)-lobed, apex acute to acuminate;

lobes divaricate to spreading or ascending, linear, arising at or below mid length, apex acute to acuminate.

3–16(–30 in fruit) × 2–5 cm;

bracts proximally greenish to dull reddish purple, distally red to orange or yellow, sometimes crimson, scarlet, orange-red, red-orange, or burnt orange, often becoming paler and/or duller with age, lanceolate to oblong, ovate, or obovate, 3–5(–11)-lobed;

lobes spreading to ascending, linear to oblong or narrowly lanceolate, medium length or long, arising at or above mid length, central lobe apex obtuse to rounded or truncate, sometimes emarginate, truncate, or acute, lateral ones acute to obtuse.

3.5–20(–29) × 1–4 cm;

bracts pale green to pale yellow throughout, or proximally pale green to pale yellow, distally pale yellow to bright yellow, sometimes light orange, light red, or bright red, lanceolate to narrowly oblong or narrowly elliptic, slightly broader than leaves, usually 3–5-lobed;

lobes ± spreading, linear or narrowly lanceolate, short or long, proximal or all bracts arising near or below mid length, apex acute, sometimes narrowly obtuse.

slightly curved, 17–38 mm;

tube 12–18 mm;

beak exserted, adaxially green, sometimes yellowish, rarely red-brown, 9–20 mm;

abaxial lip ascending, deep green, reduced, curved, 0.5–3 mm, to 10–33% length of beak;

teeth incurved, reduced, green, 0.5–1.2 mm.

straight or ± curved, 13–30 mm;

abaxial lip green or yellow, reduced, exserted or more commonly visible in cleft in calyx, 1–3.5 mm, 20–33(–50)% as long as beak;

teeth ascending, green to yellow, 0.5–2 mm.

colored as bracts, sometimes with a yellow band proximal to red to orange apices, or ca. 1/2 yellowish and 1/2 reddish, 12–35 mm;

abaxial and adaxial clefts 7–12 mm, 33–65% of calyx length, deeper than laterals, lateral 2–7 mm, 15–30% of calyx length;

lobes triangular, linear, or oblong to lanceolate, apex acute or obtuse to rounded.

proximally green, sometimes purple or pinkish, distally yellow to light orange, dull green, or colored as bracts, 11–28 mm;

abaxial and adaxial clefts 4–16(–17) mm, 30–60(–95)% of calyx length, deeper than laterals, lateral 0.5–7 mm, 4–30% of calyx length;

lobes linear to lanceolate or narrowly to broadly triangular, apex acute to acuminate.
